Write the redox reaction and predict the spontaneity for the following: a) Concentrated nitrous acid is poured on to a strip of zinc. Metals are generally oxidized and become cations while non-metals are normally reduced and become anions. This GCSE Chemistry quiz is all about one of the fundamental parts of science - chemical reactions. solution. Worksheets: General Chemistry (Guided Inquiry) ... A reaction in which one species transfers electrons to another is called an oxidation-reduction reaction, also called a redox reaction. They do all the hard work - moving here, moving there, joining this atom, leaving that atom, forming bonds, etc. 2Cs + Br2 2CsBr 4. Use Think-Pair-Share to blot all reputation in the discussions. D NO. Worksheet: predicting redox reactions using the half-reaction table 1. Si + 2F2 SiF4 8. Made by expert teachers. Reduction is the gain of electrons and the gain of negative charge. 2Li + S Li2S 3. 1) Mg + 2HCl ( MgCl2 + H2. Displacement reactions of metals (Zn with Cu²⁺, Mg with Cu²⁺). Redox reactions are therefore two-part reactions, and it’s possible to split the overall chemical equation representing a redox reaction into two chemical equations, one of the reduction, one for the oxidation.
